Activity-Based Travel Demand Modeling for Metropolitan Areas in Texas: Model Components and Mathematical Formulations (FHWA/TX-0-4080-2)

The goal of this project is to comprehensively model the activity-travel patterns of workers as well as non-workers in a household. The activity-travel system will take as input various land use, socio-demographic, activity system, and transportation level-of-service attributes. It will provide as output the complete daily activity-travel patterns for each individual in the household. In addition to the short-term activity-travel decisions, longer-term decisions about household location, employment, and auto ownership will also be considered. The implementation procedure will recognize the dynamic land use-transportation interactions. This report presents an overall conceptual framework for integrated land usetransportation modeling. The modeling of short-term activity-travel decisions and medium-term household decisions is discussed in detail. A conceptual framework is developed and is followed by representation frameworks for the modeling of short-term activity-travel patterns that will be implemented in the project. The mathematical structures of the alternate model types that are proposed for use in the project are also presented.
